Abstract: A radio frequency (RF) receiver and method of controlling an RF receiver are provided. The method includes receiving an RF signal and down-converting the RF signal to a substantially baseband signal. A direct current (DC) transition is detected in a portion of the substantially baseband signal. The substantially baseband signal is then filtered using a first filter configuration at the portion of the substantially baseband signal including the DC transition and a second filter configuration at a portion of the substantially baseband signal not including the DC transition.
